How To Remove A Stripped Spark Plug – 6 Steps

Have you ever been ready to perform some routine maintenance on your car only to find that one of the spark plugs is stripped? Isn’t that an unpleasant situation? You’re not alone, so don’t worry. For any do-it-yourself mechanic, stripped spark plugs can be a nightmare. But don’t worry! In this post, we’ll walk you through each step of how to remove a stripped spark plug without doing further harm or spending too much money.

Required tools to remove a stripped spark plug

It’s essential to have the proper tools available while attempting to remove a stripped spark plug.

How To Remove A Stripped Spark Plug

Step-by-step directions for removing that obstinately stripped spark plug safely and without any problems.

Step 1: Clean and Inspect damage

It’s essential to put off any particles from the spark plug hollow and ease the location across the stripped spark plug before trying to remove it. To gently eliminate any free debris that could damage surfaces throughout removal, use compressed air or a brush. Look for any indications of harm. Once the place has been very well wiped clean, cautiously look for any harm, which includes cracks or broken electrode suggestions.

Step 2: Use a Spark Plug Removal Tool

A spark plug removal tool, which has specifically made jaws that grab onto the spark plug and permit easy extraction without inflicting any harm, is one of the most efficient tools. With this tool, you may securely grasp the damaged spark plug and crank it counterclockwise to release and remove it from the socket.

Step 3: Apply Penetrating Oil

Applying penetrating oil may also assist loosen up a stripped spark plug that looks caught or cussed to transport. For right penetration, spritz or pour a few penetrating oils immediately onto the thread location where the spark plug contacts the cylinder head and let it sit for a couple of minutes. The oil will permeate any cracks and dissolve any corrosion or rust that is probably inflicting the spark plug to turn out to be stuck. 

Step 4: Be Patient and Gently remove

Patience is essential while working with a stripped spark plug. Rushing or using too much energy can cause engine parts to become progressively damaged or even break, necessitating expensive future repairs. If you encounter resistance or feel that spark plug is stuck then try rotating in both clockwise and counterclockwise directions while gently applying pressure to dislodge any dirt or corrosion that may be getting in the way. 

Step 5: Replace the stripped spark plug

Put in a fresh spark plug after successfully removing the old one. Fresh spark plug installation ensures optimum performance and averts any future problems. Apply a tiny amount of anti-seize lubrication to the threads of the new plug before inserting it. Future stripping will be less likely as a result, and removal will be simpler if needed.

Step 6: Use a correct-sized spark plug

Always check the proprietor’s manual for your automobile’s specifications before converting the spark plug. Your engine can be harmed or be afflicted by low fuel efficiency if you use a spark plug this is the wrong length or type. By hand, cautiously thread the substitute spark plug into the area to prevent cross-threading, which could cause greater excessive harm. When it’s far finger-tight, use a torque wrench, if essential, to tighten it to the recommended torque setting by the producer of your automobile.

How To Care For New Spark Plug

The following tips must be adopted to maintain your new spark plug.

1. Keep it clean: 

Check the plug for dirt or debris regularly, and then use a wire brush or spark plug cleaner tool to remove any accumulated dirt. Maintaining clean spark plugs promotes ideal combustion, reduces the risk of misfires, and eventually increases fuel efficiency. 

2. Monitor signs of wear: 

Check your new plugs frequently for wear indicators like eroded electrodes or excessive carbon accumulation near the tip. Early detection of these faults can help avert future engine difficulties. Because corrosion, erosion, and fouling can impair the spark plug’s ability to ignite the air-gasoline mixture inside the engine cylinders, be aware of these warning signs and symptoms. 

3. Use dielectric grease when reinstalling: 

Reinstalling your new spark plugs with some dielectric grease at the boot end helps add another level of defense against corrosion and moisture seeping into the electrical connection. By taking this easy action, you can increase the longevity and general functionality of your recently placed plugs. 

4. Read the manufacturer’s instructions: 

The design and specifications of spark plugs can differ, therefore it’s important to become familiar with the manufacturer’s unique recommendations. This will clarify for you how to properly handle and care for your spark plug. The recommendations provided by the manufacturer include vital information on torque requirements, appropriate setup methods, and any special requirements for the appropriate kind of spark plug to be used.

5. Inspect electrode gap: 

The air-fuel mixture in your engine is ignited in large part by the electrode gap. Use a feeler gauge or other appropriate equipment to regularly verify that it is adjusted correctly and by the specifications. Optimizing combustion efficiency is ensured by adjusting the gap as necessary.  

6. Securely install the spark plug: 

To prevent damage during operation, make sure that a new spark plug is firmly installed according to the manufacturer’s recommended torque specifications. While under-tightening may also lead to misfires or poor engine efficiency, overtightening can harm the threads.

7. Avoid over-tightening: 

Excessive tightening may harm the spark plug hole’s threads and make future removal challenging. Rather, turn the spark plug one more 1/8th turn to make sure it fits snugly once you feel resistance.

8. Use anti-seize lubricant: 

Before installing each new spark plug, lubricate the threads with a tiny amount of anti-seize oil to prevent corrosion and seizing in the future. If you subsequently need to replace the spark plug, this will make removal simpler. But exercise caution—applying too much anti-seize can result in fouling.


Even though it would appear difficult, getting rid of a stripped spark plug is truly doable with the proper tools and strategies. Whether you have chosen to apply a rubber band method, penetrating oil, or a spark plug removal tool, the secret is to transport cautiously and lightly. Remember to take your time and avoid speeding the technique to prevent more damage. If the entirety else fails, it’s miles constantly really useful to seek professional resources.

By cautiously following those instructions and being organized for in all likelihood boundaries, you may optimistically tackle a stripped spark plug elimination and get again on the road right away. Get to work quickly to keep away from having a stripped spark plug keep you from playing your car.

First, apply penetrating oil around the base of the spark plug and let it sit for at least 15 minutes. Then use steady pressure with a socket wrench in an attempt to loosen it slowly. If it doesn’t budge, try tapping gently on the end of the wrench with a rubber mallet to break any corrosion.

How often should you replace your spark plug?

When you attain a distance of 30,000 miles, whether you have popular spark plugs or lengthy-existence spark plugs determines the life expectancy of your engine. The maximum variety for a typical automobile is between 30,000 and 50,000 miles. The latter calls for replacement between 60,000 and a hundred and fifty,000 miles.

What occurs if your spark plugs aren’t changed?

Your car is not able to transport or feature in any manner. Spark plugs play an essential function inside the engine cycle, reworking gas into mechanical work. Therefore, the engine cycle cannot take region without spark plugs. Studies show that your spark plugs’ situation suggests your engine’s normal health.
